The cylinders may be connectedtogether in any preferred manner, but are herein shown connected Vinseries by pipe Sections 18 which are tapped into opposite portions ofthe cylinders, as shown in Fig. 3., The piping '18 is connected with' apump or other suitable source of hydraulic pressure.

Supported on the hearing plate 17 is a track comprising channeled Arails`1,9 and 20 connected iat intervals by cross bars 21, which serve tostrengthen and prevent-indef .l pendent movement of' the rails. Lateral75 movement of the track is prevented by means of hearing piates 22.secured tol the .outer` surfaces of the rails, 19` and 20, and theouter end portions of which are provided with heads 24' which hear onvertical metal 30' strips 25 embedded in the aidew'alls t3 and 7..

the said beams. The end of the steel yard remote from the fulcrumthereof is provide-d with a yoke 51 and connection between this yoke anda clevis 52 on the scale beam is establishedby means of a link 53.

Arranged on the upper surface ofr the flooring 3l and extendinglongitudinally of the pit are chock blocks 54 and 55. These blocks arearranged at the opposite ends of the platform so as to engage theflanges of oppositely disposed wheels when the flooring moves upward. i

ln' use and assuming that the total weight of a locomotive is tobedetcrmined, as many scales are placed upon the rails 19 and 20 asthere are wheels on one side 'of the loco- .niotive These scales arethen adjusted along the track until the chock blocks are in alineinentwith the vertical centers of the wheels` l I, after 'which liquid isforced into the cylinders, y'a'hereupon the plungers, track and scaleswill move upward. During the upward movement et these parts the blockswill engage the anges 5G 'ot the wheels and the latter with the partsthey support will be moved to the position shown in Fig. 4. The weighingof the locomotive can now be effected. lVhcn it is desired to determinethe weight. supported by any particular pair -3 or pairs of'wheels therequired number of driven by any suitable motive power capable ol'moving it in either direction.
